It retrieves a remote binary, writes it to a temp directory, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T17:49:51.553Z - **Finished:** 2026-08-05T17:50:11.808Z - **Download time:** 252 ms - **Static scan time:** 44 ms - **AI review time:** 19956 ms - **Total time:** 20255 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately invokes a hidden compatibility loader. It retrieves a remote binary, writes it to a temp directory, and launches it detached. - **Trigger:** Any runtime require/import of the main entrypoint. - **Impact:** Arbitrary remote code executes as the importing process user. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:50:11.808Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** The main entrypoint silently requires \_compat.js, which runs immediately. It downloads a platform-specific payload from rotating worker hosts or reconstructs one from DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and starts it detached through a shell or cmd.exe. - **Rationale:** This is a concrete import-time staged payload execution chain, not package-aligned telemetry. The unused-looking telemetry module contains a parallel configurable downloader/launcher design, reinforcing intent. - **Files touched:** index.js, \_compat.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_compat at module load., \_compat.js downloads platform binaries over HTTPS., \_compat.js falls back to DNS TXT payload retrieval., Downloaded bytes are written to temp and executed detached., Remote hosts are obfuscated and unrelated to package purpose. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or AI-agent config writes found. ## Public findings ### 1.
